HERBERT E. BROWN, OF HOUSTON, TEXAS.
Specification of Letters Patent. Patented Mar. 11, 1913.
Application filed May 6, 1912. Serial No. 695,340.
To all whomit may concern:
Be it known that I, IIERJRT E. BROWN,
a citizen of the United States, residing at
Houston, in the county of 1-arris and State
5 of Texas, have invented certain new and
useful Improvements in Churns, of which
the following is a specification.
My invention relates to new and useful
improvements in churns.
10 The object of the invention is to provide
a device of the character described, having
a plurality of rotatable agitators arranged
in the milk receptacle and means for rotat-
ing said agitators.
15 Another object of the invention resides
in the provision of a securing means for se-
curing the agitators to the rotating mecha.-
nism whereby said agitators may be readily
removed from the receptacle, when it is de-
20 sired to cleanse the same.
With the above and other objects in view,
the invention has particular relation to cer-
tain novel features of construction, opera-
tion and arrangement of parts, an example
25 of which is given in this specification and
illustrated in the accompanying drawings,
Figure 1 is a side elevation of the com-
plete device, showing the milk receptacle
30 in section. Fig. 2 is a fragmentary perspec-
tive view of the agitators secured to the ro-
tating means. Fig. 3 is a diagrammatic
fragmentary view of the agitator support.,
and Figs. 4 and 5 show, respectively, the
35 upper ends of the agitator rotating means.
Referring now more particularly to the
drawings wherein like numerals of refer-
ence designate similar parts in each of the
figures, the numeral 1 refers to a milk re-
40 ceptacle, whose bottom has a central orifice,
surrounding which is the upstanding sleeve
2, which is secured to the bottom of the re-
ceptacle and which projects upwardly into
the same. The milk receptacle has a suit-
45 able covering 3.
The milk receptacle is designed to rest
upon a suitable platform 4, preferably
formed of cast metal and this platform is
designed to be secured to a table or other
50 suitable support 5 by means of the hand
screw 6, in the ordinary and well known
manner. Depending from the platform 4
and cast integral therewith are the bearings
7 and 8 vertically alined with each other and
55 rotatable in said bearings is the vertical
shaft 9 which extends upward through the
sleeve 2. Resting upon the bearing 7 and
surrounding the. shaft 9, within the sleeve
2, is the hollow' shaft 10. Rigidly secured
upon the lower end of the shaft 9 is the 60
pinion 11 and rigidly mounted upon the
shaft 10 is the pinion 12 and meshing with
said pinions is the bevel gear wheel 13
mounted in a suitable bearing in the casting
14 which depends from the platform 4 and 65
supports the bearing S. This bevel gear
wheel is provided with a crank 15 through
which the same is rotated. The rotation of
the bevel gear wheel 13 imparts relative ro-
tation to the pinions 11 and 12, but in op- 70
The numeral 16 refers to a socket member
which is designed to fit over the upper end
of the hollow shaft 10 and which is provided
with a vertical slot 17 whose upper end has 75
a lateral extension. The pin 18 carried by
the upper end of the shaft 10 passes up the
slot 17 and engages in the lateral extension
of the upper end thereof and the socket
member 16 is thus secured on said shaft 80
while the shaft rotates, but may be readily
detached therefrom. A socket member 19
is also provided which fits over the upper
end of the shaft 9 and which engages in a
similar manner with the pin 20 carried by 85
the upper end of said shaft. The socket
-members 16 and 19 are provided with hori-
zontal rods 21 and 22 which extend each
way therefrom and from the free ends of
which depend the respective agitators 23, 23 90
and 24, 24 which are paddle shaped mem-
bers and which extend almost to the bottom
of the milk receptacle.
It is obvious, when the crank 15 is turned,
the shafts 9 and 10 will be rotated in. the 95
opposite direction through the gear wheel 13
and the pinions 11 and 12 and the agitators
23, 23 and 24, 24 will accordingly sweep
around through the milk receptacle in op-
posite directions and will thoroughly agitate 100
the milk, with the result that the butter will
be quickly separated therefrom.
While I have shown only one form of this
device, it is apparent that various changes
may be made in the mechanical construction 105
thereof and I hereby reserve the right to
vary the construction thereof, so long as I do
not depart from the principle as set forth in
the appended claims.
What I claim is:- 110
1. A device of the character described in-
cluding a suitable support and a milk recep-
